Sourdough Cheddar Snack Crackers

The sound of my food processor whirring with cold butter and sharp cheddar has become my favorite afternoon ritual, mostly because it means I found another excuse to use up sourdough discard. These little golden squares have a way of disappearing before they even make it to a proper snack bowl. My roommate once stood in the kitchen eating them warm off the tray and declared them dangerous. I have been making them weekly ever since.

I brought a tin of these to a potluck last fall and watched people skip the fancy cheese board entirely to hover near the crackers. One friend assumed I had ordered them from some artisan bakery online. There is something deeply satisfying about handing someone a homemade cracker and watching their eyebrows go up.

Ingredients

• All-purpose flour (120 g): Provides the structure without making them tough, and you do not need anything fancy here.
• Sourdough discard (100 g, unfed): This is the star, bringing tang and depth that makes these taste far more complex than the effort suggests.
• Unsalted butter (115 g, cold): Keep it cold and diced so it creates those tender flaky layers as it bakes.
• Sharp cheddar cheese (120 g, grated): Sharp is nonnegotiable because a milder cheese will get lost in the dough.
• Fine sea salt (1/2 tsp): Enhances every other flavor without overpowering the cheese.
• Garlic powder (1/4 tsp, optional): A quiet background note that makes people ask what your secret is.
• Smoked paprika (1/4 tsp, optional): Adds a whisper of smokiness that pairs beautifully with the cheddar.
• Flaky sea salt for topping: That finishing crunch on top is what makes them feel bakery worthy.

Instructions

Blend the dry ingredients:

Pulse the flour, salt, garlic powder, and smoked paprika in your food processor a few times until evenly mixed. Toss in the cold butter pieces and pulse until the mixture looks like coarse crumbs with some pea sized bits remaining.

Add the cheese:

Scatter the grated cheddar over the crumbly mixture and pulse just enough to distribute it evenly throughout. You want to see tiny flecks of cheese in every handful.

Bring in the discard:

Add the sourdough discard and pulse until the dough starts clumping together into a cohesive ball. Stop as soon as it holds together because overworking it will make the crackers tough instead of tender.

Chill the dough:

Turn the dough onto a lightly floured surface, shape it into a flat disc, and wrap it snugly in plastic. Let it rest in the fridge for at least 30 minutes so the butter firms up and the dough becomes easier to roll.

Prep for baking:

Preheat your oven to 180°C (350°F) and line two baking sheets with parchment paper. Give the dough a few minutes at room temperature if it feels too firm to roll.

Roll and cut:

Roll the dough out to about 3 mm thick, then use a knife or pizza cutter to slice it into 2.5 cm squares. Transfer them to the prepared sheets, leaving a small gap between each one.

Prick and salt:

Prick each square once or twice with a fork to keep them from puffing up unevenly. Give them a light sprinkle of flaky sea salt right before they go in.

Bake until golden:

Bake for 20 to 25 minutes, rotating the trays halfway through so they brown evenly. You want them deeply golden at the edges for maximum crunch.

Cool completely:

Let them cool on the trays until they reach room temperature, which is when they reach peak crispness. Try to resist eating them all warm, though no one will blame you if you do.

Save

There was a rainy Saturday when I made these purely out of boredom, and they ended up being the reason three neighbors came over for impromptu soup night. Sometimes the best meals start with a handful of crackers and no plan at all.

Storing Your Crackers

Keep them in an airtight container at room temperature and they will stay crisp for about a week. If they soften over time, a quick ten minute toast in a 160°C (325°F) oven brings them right back to life.

Flavor Variations Worth Trying

A pinch of cayenne pepper scattered into the dough adds a slow warmth that builds with each cracker. You can also swap the cheddar for Gruyère if you want something nuttier, or use half Parmesan for a more savory punch.

Serving Suggestions

These crackers shine on their own but truly elevate a snack spread when paired with the right accompaniments. Think of them as the foundation for whatever you are craving.

• Pile them alongside hummus or a sharp mustard for an effortless afternoon snack.
• Crumble a few over tomato soup for a crunchy garnish that beats regular croutons.
• Pack them in lunchboxes as a homemade alternative to anything from a package.

Save

Every batch feels like a small victory over food waste, and honestly, they taste too good to call a leftover hack. Share them freely, guard the recipe closely, and always make extra.

Recipe FAQs

→ Why use sourdough discard in the dough?

Sourdough discard adds tang and depth without extra steps. Its hydration helps bind the dough and contributes subtle acidity that balances the sharp cheddar, giving a more complex savory bite.

→ How thin should I roll the dough for optimal crispness?

Roll to about 3 mm (1/8 inch). Thin pieces bake evenly and become crisp; thicker pieces stay a bit tender. Uniform thickness ensures consistent browning across the batch.

→ Can I substitute other cheeses for cheddar?

Yes. Gruyère, Parmesan, or a sharp white cheddar work well. Hard, aged cheeses add nuttiness and crisp texture; softer cheeses may make the dough greasier and less crisp.

→ What if my crackers are still soft after baking?

They often crisp more as they cool. If still soft after cooling, return them to the oven for a few minutes at a lower temperature or bake a few extra minutes during the initial bake, watching closely to avoid burning.

→ Is a food processor necessary, or can I use a pastry cutter?

A food processor speeds the job and gives a very even crumb, but a pastry cutter or two knives to cut in cold butter works fine. Keep everything cold and avoid overworking the dough to maintain flakiness.

→ How should I store the crackers to keep them crisp?

Cool completely, then store in an airtight container at room temperature with a paper towel to absorb any residual moisture. Properly stored, they stay crisp for several days.
